This year, an estimated 67,790 people were diagnosed in the U.S.One research team led Iowa State University has made a discovery that could potentially lead to better treatment and cure of leukemia. Since then, she found that protein, in combination with signaling pathway JAK2/STAT3, can effectively create and differentiate white blood cells. This would then prevent bone marrow from further filling up with leukemia cells. “[In leukemia], your body is not making white blood cells at the rate that it should. Espin Palazon said many current treatments block the JAK2/STAT3 pathway entirely, but that makes the cells proliferate and further divide.
